Auxiliary Connection For Power Failure Transfer - Panasonic KXTA308 - ANALOG PBX Installation Manual

2.5 Auxiliary Connection for Power Failure
Transfer
Feature References
Power failure transfer connects a specific single line telephone to
the selected outside (CO) line in the event of system power failure,
as follows.
Outside (CO) Line 1 – Extension (T, R) Jack 01
Connection of outside (CO) line 1 and the respective extension
requires no auxiliary connection.
Note • In the event of a power failure, system memory is protected by a
factory-provided lithium battery. There is no memory loss except the
Camp-on, Saved Number Redial, Last Number Redial, Call Park and
Message Waiting memories.
• The system automatically changes the current connection to the above
connection when the power supply stops.
• Proprietary telephones cannot be used during a system power failure.
Therefore, we recommend connecting a single line telephone in parallel
with the proprietary telephone connected to JACK 01.
